PHOTOLYSIS OF 3-OXO-Δ5(10)-STEROIDS IN ALCOHOLIC SOLVENTS AND IN THE SOLID PHASE

Williams, John R.,Abdel-Magid, Ahmed

, p. 1675 - 1678 (2007/10/02)

Irradiation of the β,γ-unsaturated ketone 1a in alcoholic solvents afforded the 1,2 and 1,3-acyl shift products 2a and 3 respectively.The cyclobutanone 3 underwent further photochemistry incorporating a molecule of solvent and affording the ring expanded cyclic acetal 6.Solid phase irradiation of 1a yielded 2a and 3 but 1b was photostable.
